MAINTENANCE
• The garage jack should be lubricated once
a month. Aluminium oxide and rust can
cause the jack to lift more slowly and can
damage its internal parts.
• Lubricate all moving parts with thin oil.
• Visually inspect the jack for deformation,
cracks in or beside welds, leakage of
hydraulic oil, and for damaged, loose,
worn or missing parts.
• If the jack has been exposed to abnormal
loads or knocks, or if vibrations or
abnormal noise occur when in use it must
be checked. We recommend taking the jack
to an authorised service centre to be
checked. Clean all the surfaces and make
sure that the rating plate and safety and
warning labels on the jack are intact and
legible.
• Check the oil level in the jack, and top up if
necessary.
• Check the jack for corrosion every three
months. Clean when necessary and rub
with an oiled rag. When the jack is not in
use the saddle should be in its lowest
position.
WARNING!
• Never fill the jack with any other oil than
a recommended jack oil. The use of other
oil can damage the seals.
• Never use hydraulic brake fluid, engine
oil, dirty or contaminated oil, lubricant or
other liquids.
Checking the oil level
1. Turn the relief valve anticlockwise so that
the piston goes in all the way. Press down
the saddle, if necessary.
2. Place the jack on a level surface and
carefully remove the oil filler plug.

3. The oil should reach up to the lower edge
of the filling hole. Do not overfill when
topping up with oil. Only use new, clean
jack oil.
4. Replace the oil filler plug.
5. Function test the jack.
6. Bleed, if necessary.
Bleeding
During transport and when in use air can
sometimes get into the hydraulic system on the
jack. This can reduce the lifting capacity of the
jack and means that it needs bleeding.
1. Open the relief valve fully by turning it
anticlockwise.
2. Pump eight full strokes with the handle.
3. Close the relief valve by turning it clockwise.
4. Pump with the handle until the piston is
fully out. Pump a few more times to drive
out any air.
5. Carefully unscrew the oil filler plug a little to
release the air.
6. Open the relief valve by turning it
anticlockwise one full turn and lower down
the jack completely. Press down the saddle,
if necessary.
7. Turn the relief valve clockwise to closed
position and function test the jack. Repeat
the above steps if necessary to bleed it more.
